My ~16 year old male normally is tease-fed and strikes a few times and then grabs on and eats anything without trouble. I've tried feeding him defrosted mice and fish slices (which he eats frequently) and all he does is strike at the food about 5 times and then lose interest. The house is kind of cold (mid-low 60s) so that's the only change I can think of, but it's never been an issue before and the light cycle hasn't changed. It's been about 1.5-2 weeks since he last ate (on the high end of normal), and I've been trying for the past 3 days. Weight still seems normal so not necessarily an emergency. Any advice? Thanks
